Letters Patent No. 101,667, dated April 5, 1.870.

IMPROVEMENT IN CAR-BRAKES.

The Schedule referred to in these Letters Patent and making part of thesame To all whom at may concern Be'it known that I, GEORGE H. SEYMOUR,of Newark, in the county of Licking and in the State of Ohio, haveinvented certain new and useful Improvements in Gar-brakes; and dohereby declare that the followingiis a full, clear, and exactdescription thereof, refcrence being had to the accompanying drawingsand to the letters of reference marked thereon, making a part of thisspecification. v

The nature of my invention consists in the construction and arrangementof a f lever car-brake, by the use or which the brakes will operate onboth sets of trucks, or on the whole eight wheels of the carsimultaneously, as hereinafter more fully described.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now'proceed to describe itsconstruction and operation, referring to the annexed drawings, inwhich-- Figure 1 is a side view of the car with my brake attached.

Figure 2 is a bottom view of the same; and

Figure 3 is a front view of one of the brake-shoes, or clogs.

Figure 4 is a longitudinal section showing the bar G and itsconnections.

A represents the platform of the car, and

B B the wheels.

Upon the right or left hand corner of either end of the platform A, issituated a hollow upright, G, in the top of which is a Windlass, theshaft of which is provided with a crank, D, ratchet-wheel, a, and pawl,12. To the windlass is attached a chain or band, which passes down thehollow upright 0, through the platform A, where it is attached to oneend of the lever E, which is hung in the middle from the bottom of thecar.

The other end of the lever E connects at right angles with the lever G,situated under the middle, and running lengthwise of the car. The leverG crosses and is firmly fastened to the transverse bar H, which extendsout even with and half way between the wheels BB, on either side of thecar, and is fastened to the truck-beam in such manner as to allow it toturn. On either end of the bar or shaft H are placed the cams -11,constructed with beveled ends, as shown-in fig. 1.

By turning the crank 1) the band or chain winds around the Windlass,drawing up the end of the lever E, to which it is attached, and throwingdown the lever G, turning the transverse bar H, and bringing the ends ofthe cams d against the projecting bars 0, attached to the clogs or shoesI, and thus pressing the clogs agaiustthe wheels.

The bars 0 c are adjustable, being attached to the clogs by sliding intoa dovetail-shaped groove, and are held in place by a screw passingthrough the bars and pressing against the face of the clogs. By

loosening the screw the bar 0 can he slid up or down,

thus bringing it nearer to or farther from the ends of the cam 11. Thebars 0 are of steel, and intended to spring or give under a pressureexceeding that sufiicient to block the wheels.

Theclogs I I are hinged to the ends of the bar J, which is firmly boltedto the truck-beam, and the clogs are held from. the wheels when thebrake is off by the spring 1 pressing against their lower ends.

The levers G G extend from the transverse barsH H to half way waybetween the two sets of trucks, Where they join, as shown at :0, so thatthe power being applied at either end of the car will operate the brakesof both trucks, and will apply them to the whole eight wheels of the carsimultaneously.

Having thus fully described my invention,

\Vhat I claim new, and desire to secure by Letters Patent, is-.-

I. The clogs or shoes I I provided with adjustable steel-spring bars, ee, substantially as and for the purposes herein' set forth.

2. The combination of the clogs I I and spling -i;.

the clogs being hinged to the bar J, substantially as shown anddescribed.

3. The combination of the levers E and G G, transverse bars H H, andcams ll (Z, all constructed and arranged to operate substantially in themanner and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this20th day of December, 1869.

- GEO. H. SEYMOUR.
